Changing the eSlick text font

On the Foxit eSlick Forum are various somewhat unclear instructions for changing the text font. To be explicit, the steps are:
1. Create a folder named "Fonts" in the root folder of the eSlick's internal memory.
2. Find a Truetype font, i.e. a *.ttf font - I used the Gentium Book Basic font.
3. Rename "GenBkBasR.ttf" (or whatever) to "fxfont.ttc" and copy it to the "Fonts" folder.
4. Reset the eSlick by depressing the recessed Reset switch on its back whilst it is powered on.
